rosTER BOARD.

Application filed June 8,

v The invention rela'tes to poster boards upon which advertis ng inatter is displayed,

usually by pasting sheets of paper upon which the matter, pictorial, descriptive, or otherwise, is printed.

"It is customary to clear the poster board at intervals, this being accomplished by means of ascraper. As ordinarily con stiaictetl the metal sheets forming the surface of the poster board overlap and are attached to the supporting structure by nails (lllVIl through the overlapped portions of the'sheets. When scraping the board to remove the old jbilhjo'r advertising sheet, the

nails are frequently dislodged and require and which'is strengthened and braced by having edge portions of the metal sheets bent at a right angle, jbu'tted and attached to the supporting structure.

The invention furthermore provides sec- .tions which are attachable'to the support ing Jstructiire, each of such section's consisting of a batten frame and sheet metal attached'thereto, the section being preferably provided along a butting edge with an olfstanding flange to overlap the joint formed between adjacent sections.

lVhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in" adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the inven tion as claimed, without departing from the spirit thereof.

For a full understanding of the inven tion and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,-

Corresponding and like parts are referred to in the following"description anddesigend portions. of adjacent sheets, thesaine by like reference characters;

The poster board includes a supporting structure,which, as shown comprises 1, braces l and'stringersQ. The uprights 1 be of any height-and spaced-apnea 5 determinate distance. poster] board comprises sheets which are attached to the batten frames formingfisection'sl 'Us'iiailly, the uprights '1 are's'pac'ed apart spohding to the combined width (if two metal sheets. Each section or paner rferably includes two metal sheets which are reinforced and strengthened by means or battens posed horizontally between the bat-tens which in practice are disposed vertically. Cleats 5 nds conned the bridges. andiipr rights. are nailed or other v The surface of "the The cleats 5 wise secured to the intermediate battens of each section or panel and their endpoitions project so as to overlap ends of the bridges 4 a; hich they are, nailed or otherwise made fast,

end battens 3 and the adjaceiiten'ds of the bridges 4. The bridges 4 are disposed upon and between The sides of the opposite sides of the battens 3 it and the battens 3.

battens and bridges facing the metal sheets come flush with and are in contact with the metal sh eets, so as to strengthen and reinforce the same.

The numeral 7 designates the-metal sheets which may be of any width and which usually are of a length corresponding to. the height of the poster board,as shown most clearly in Figure 1. The longitudinal edge portions of the metal sheets 7 are bent in the same direction at a right angle, as in receive the nails, or like fastenings whereby the sheets are attached to the battens 3 and 3" by being driven through the fianges,'as indicated most clearly in Figure 3. The battens are located in the angles formed between the sheets and the bent edge porof the drawings so a distance cone 7 and bridges 4, the latter'being'dis- :75

the adjacent" K. a'fs Gare nalled or otherwise secured "to the tions 8 thereof. An outer edge portion of a sheet of each section or'panel has a portion bent outwardly, as indicated at 9, to overlap the joint formed between adjacent panels or sections. The surface of the poster board comprises panels or sections and each of the panels comprises two metal sheets 7. A batten 3 is located at the meetportions ing edges of the two sheets comprising a panel, and a batten 3 is located at the outer edge of the panel, as shownjmost-clearly in Figures 2 and 3. End portions of the inner flange 8 of one of the sheets? of a panel are cut and project, .as indicated at 10, to overlap end portions of the adjacent sheet to which they are secured and to the bridge pieces means, as'indicated most clearly in Figure by nails or suitable fastening 1. After the panels have been placed in po-, sition the poster board is finished by applying a molding l1 thereto which provides a frame around the ends and the top and bottom thereof.

It will be understood from the foregoing that the poster board presents asmooth surface which is free from projecting nai heads and overlapping edge portions, hence old posters may be readily removed, without endangering the surface to such an extent as to require repair. The fastenings securing the panels or sections to the intergage the side of a ting flanges areattached, one of the flanges having end portions cut and extended outwardly from the sheet substantially in the plane thereof to overlap and ,engage the outer side of the adjacent sheet to which they are attached.

2. A poster board panel comprising metal sheets having their longitudinal edge portions bent laterally in the same direction to provide reinforcing and attaching flanges, adjacent sheets having the inner contiguous flanges abutting, a batten disposed in the angle formed between asheet and the said abutting flanges and having the latter secured thereto, otherbattens arranged in the angle formed between the outer flanges and the sheets and attached to the said flanges, bridge pieces between the battens, and means connecting oppositely disposed bridge pieces to one another and to the battens.

3. A poster board panel comprising metal sheets having their longitudinal edge portions bent laterally in the same direction to provide reinforcing and attaching flanges, adjacent sheets having theinner contiguous flanges abutting, and one of the abutting flanges having 'end portions cut and extended outwardly therefrom about in the plane of the panel, a battenvin the angle formedbetween a sheet and the said abutting flanges and having thelatter and the said end extensions of a flange secured thereto, other battens arranged in the angle formed between the outer flanges and the sheets and attached to the said flanges, and

bridge pieces between the battens and connected thereto and to one another.
